Basic Rules of the Class Room

These rules are designed to allow students to get the maximum benefit for their time and money spent.
The physical attendance of lectures is not required but strongly recommended. If you happen to be late, enter class, do not apologize, quietly take your seat and start working. If you need to leave, do so also as quietly as possible, do not ask permission.
Do not talk in class even in a low voice since it is disruptive (asking a fellow student a brief question is admissible, but should be kept to the minimum). Do not hesitate to interrupt the lecturer with any questions or comment, since it is beneficial for the class. (Do not assume that your question is too trivial to ask -- it may well be not so trivial. Many students may have a similar problem. No questions and comments in class will affect your grades in any way.)

SYLLABUS

Description

Nano-optics deals with optical phenomena and spectroscopy on the nanoscale, i.e., in the regions of space whose size is much smaller than light wavelength. While an electromagnetic wave cannot be localized in regions with the sizes significantly smaller than half wavelength, nano-optics is based on electric fields oscillating at optical frequency. As optical interactions with matter and spectroscopy are concerned, such local optical fields, in most cases, produce the same type of responses as electromagnetic waves. Elementary excitations that are carriers of energy and coherence in nanooptics are surface plasmons (SPs). These excitations exist at surfaces of metals whose dielectric functions are negative. The SPs are purely electric excitations that can and do localize on the nanoscale creating highly concentrated and resonantly enhanced local electric optical fields. These local fields cause a wealth of gigantically enhanced optical phenomena of which the surface enhanced Raman scattering (SERS) is the most studied and widely known. This course will encompass the fundamental properties and applications of the surface plasmonics at the nanoscale. It will include coherent effects associated with phase memory of the SPs, in particular, coherent control of nanooptical phenomena. Nonlinear processes, for instance, generation of harmonics and two-photon excitation by nanoscale fields will also be covered. Ultrafast (femtosecond and attosecond) phenomena are within the scope of this course. We will also include quantum phenomena associated with SPs as quantum quasiparticles, such as quantum generation, amplification and quantum fluctuations. Along with fundamental properties of SPs, we will consider the many applications of nanoplasmonics, in particular, detection of ultrasmall amounts of chemical and biological compounds, scanning near-field optical microscopes (NSOMs or SNOMs), and nanolithography.
